[TYPO3] missing fields after update

[Bernd Wilke]

hello,

we just updated an installation from 4.0.2 to 4.1.2 because we wanted 
the new accessibility options of the content-element table. (

but after the update (and table compare) there are still no 
accessibility-options for table.
Maybe this installation was a former version 3.8, but there is no 
compatibility mode.

in the configuration -> TCA there still is

$TCA['tt_content']['types']['table']['showitem'] = 
'CType;;4;button;1-1-1, header;;3;;2-2-2, layout;;10;button;3-3-3, cols, 
bodytext;;9;nowrap:wizards[table], text_properties';

instead of

$TCA['tt_content']['types']['table']['showitem'] = 
'CType;;4;button;1-1-1, header;;3;;2-2-2, layout;;10;button;3-3-3, cols, 
bodytext;;9;nowrap:wizards[table], text_properties, pi_flexform;;;;1-1-1';
(This is from another 4.1.2 installation)

my question:
where and what has to be changed to get the accessibility-options for 
content-elements table?

I know I could change this entry in extTables.php, but I think it comes 
somewhere from core and there must be more than only the field pi_flexform.
Which files should I inspect for differences?

Bernd
